One of the fringe benefits of the Wisconsin Book Festival is that local bookstores order up the titles of the fest's featured authors.

That's how I picked up in San Francisco; the in Iowa City. But just as satisfying, maybe even more satisfying in a way, is finding the very appealing shops that are, in comparison, in the middle of nowhere: in Richland Center, for instance.
I found that The Yellow-Lighted Bookshop went well with the autumn leaves and a sunny Saturday afternoon spent reading on the porch, but it would also pair nicely with a roaring fire and a dog or cat on your lap.
